Abstract

PURPOSE: To obtain a surface protective agent for eliminating stains at non-image portion by diffusing alkali soluble resin into the aqueous solution of water soluble high molecular compound, thereby increasing the fat unsensitivity at the non-image portion without decreasing the fat sensitivity at the image portion.
CONSTITUTION: Preferably 0.1W20 wt% of an alkali soluble resin such as phenol formaldehyde resin and polyhydroxystyrene is diffused into the aqueous solution of a water soluble high molecular compound such as a water soluble cellulose ether. If desired, for example, 0.1W0.5 wt% of moistening agent such as polyhydric alcohol may be further added. It is preferable that the above-stated water soluble high molecular compound should be of 10W20 wt%.
